Years into the controversy around how to scale Bitcoin, there have been many challengers to Bitcoin core’s dominance. After XT, Classic and others have faded, Bitcoin Unlimited has been gaining traction and emerged as plausible new way forward.
Bitcoin Unlimited wants to make the block size a parameter that is set by miners and nodes, but not fixed at a network level. They argue a natural fee market would emerge, allowing Bitcoin to rapidly scale and realizing its promise of electronic cash as well as store of value. The project is also member-driven, with democratic decisions driving its development decisions.
Core developer G. Andrew Stone and Bitcoin Unlimited President Andrew Clifford joined us for the episode.

Ari Juels, a Professor at Cornell Tech (Jacobs Institute) and former Chief Scientist of RSA, joins us to discuss his work two of his blockchain-related research topics: Authenticated Data Feeds for Smart Contracts and criminal smart contracts.
One of the shortcomings of decentralized smart contracts is their inability to retrieve information from the outside world. Smart contracts can’t make API calls to websites and data feeds, but rely on oracles to feed real-world information to the chain. This potentially requires a high trust in the oracle operators. Authenticated data feeds promise to solve the problem by relying on Intel’s novel SGX hardware.
We also talked about how criminals could use smart contracts to more efficiently conduct crimes such as incentivizing the theft of private keys or even soliciting real-world crimes such as murder.

Roger Ver is one of the earliest Bitcoin investors and through his tireless evangelizing of the cryptocurrency became known as ‘Bitcoin Jesus’. Roger joined us to discuss Bitcoin’s incredible potential to foster liberty. We also discussed how the current stalemate about how to scale Bitcoin is threatening that potential. And, finally, the mining pool operated by his site Bitcoin.com that is supporting the Bitcoin Unlimited client.

Few crypto projects have gotten as much attention and caused as much controversy as Steem. The blockchain-based social media platform launched early this year and managed to gain real user traction building up a vibrant community of contributors. The Steem token quickly entered bubble territory reaching a market cap of almost $400m and losing 90% of its value since.
Steem Co-Founder and CEO Ned Scott joined us to discuss the ambition of the project and its short tumultous history. We also discussed some of the accusations against Steem and its unorthodox launch.

In their relatively short lifespan, blockchain technologies have already undergone significant milestones. Bitcoin’s blockchain, often referred to as Blockchain 1.0, features a simple database ledger that records transactions in a chronological order and represents the state of the network to participants. Ethereum, or Blockchain 2.0, introduced the notion of smart contracts. Microsoft’s Bletchley Project introduces a new modular architecture which might mark a new milestone for blockchain technologies.
Marley Gray, Principal Program Manager Blockchain at Microsoft, joins us to talk about Microsoft’s approach to blockchain architecture. With enterprise in mind, Bletchley introduces the concept of “Cryptlets”, the core building blocks for introducing a secure middleware tier into blockchain application infrastructure. These computational units, running off-chain, on secure trusted container enclave hardware, could provide trusted data to on-chain smart contract logic.

System scalability and extensibility of system features are two central problems around which research in the cryptocurrency / blockchain industry has centered. For example, the Blockstream sidechains project foresaw hundreds of blockchains coordinating together to form an ‘Internet of Chains’ delivering extensibility to the Bitcoin system.
Recently, Dr. Gavin Wood, co-founder of Ethereum and Parity, put forth Polkadot, a technical vision to achieve the similar end-goals using different system architecture. Polkadot could enable individual blockchain networks to share security and communications infrastructure with other blockchain networks, forming in effect an ‘Internet of Blockchain networks’.
Melonport, a team based out of Zurich, has taken up the challenge of deploying the Polkadot network and also building decentralized asset management software on the same network. In this episode we converse with Mona El Isa and Reto Trinkler, co-founders of Melonport, in order to discover more about the overall vision.
